Secondary Market Data
Live order book, trade history, and order history across the most actively traded private companies — plus our proprietary MarketPrice estimate built from real flow.
Funding Rounds
Round-by-round amounts, valuations, participants, and source citations. Pull a single round, a company history, or the global updates feed as new rounds are confirmed.
Company Firmographics
Company profiles, COI filings, stock splits, fund marks from SEC filings, news with sentiment, and quarterly market summaries.
Investor Data
Investor participation across funding rounds — the funds, firms, and individuals on the cap tables of every covered company.
Comps & Indices
Comparable-company performance and composite index timeseries, sliced by sector and vertical for benchmarking late-stage marks.
Company Signals
Revenue, headcount changes, hiring trends, customer wins, and product milestones — the operating signals that move private-market valuations between rounds.
